Abstract

Genetic linkage studies were conducted in four multigenerational families with X-linked Charcot-Marie-Tooth disease (CMTX), using 12 highly polymorphic short-tandem-repeat markers for the pericentromeric region of the X chromosome. Pairwise linkage analysis with individual markers confirmed tight linkage of CMTX to the pericentromeric region in each family. Multipoint analyses strongly support the order DXS337-CMTX-DXS441-(DXS56,PGK1).

摘要

对四个患有X连锁型夏科-马里-图斯病(CMTX)的多代家庭进行了基因连锁研究,使用了12个高度多态性的短串联重复序列标记来研究X染色体的着丝粒周围区域。对单个标记进行的成对连锁分析证实了每个家庭中CMTX与着丝粒周围区域紧密连锁。多位点分析有力地支持了DXS337-CMTX-DXS441-(DXS56,PGK1)的顺序。
